Normally when someone swipes every string change it sounds a little dirtier than you’re getting. Even Batio who uses it systematically, you can still hear it, and his left hand muting is pretty tight. In your case, I can’t really hear it, to be honest, nor can I see it, but that could be a video issue. Either way I would guess that if it’s happening, it might not be happening all the time.
Without overthinking this, the most straightforward approach here is to assume the arm position that we know works for for mixed escape, which is very similar to what you’re already using anyway. Here’s a great live shot of Al Di Meola where you can see the anchor points super clearly:
The spot where the pinky heel meets the wrist, that touches the bridge. That’s it. Once you have that, all motions are done from this position, no rolling the arm around. The shot at :53 is a great example of exactly what that looks like:
Once you have this, you can try some phrases that mix notes per string and see how smooth you can get them. You don’t have to jump right into bluegrass roll patterns. You can try patterns that have mixtures of 3nps, 1nps, and 2nps. Lines like what Al is playing in these clips work well. I also like 212 patterns like Andy is playing here, because they can feel more obvious when you hit wrong strings / notes:
Finally, if you are concerned about interference from existing learned motions and you want to try something new, I have only very positive things to say about EVH style motion with the middle- and three-finger grips. Have you taken the table test in our latest update? Since you are already good at wrist motion I would think you’d have no problem with the EVH style.
If you really want to break out of the rut, see if you can tool around with the EVH style and find a way for it to feel comfortable. It may require experimentation. But if you want to get out of the comfort zone / baggage, that’s a great way to do it.
